Students will review:
In this chapter, you'll learn the answer to questions including:
- How do speed and velocity differ?
- What is acceleration?
- What do Newton's laws of motion state?
- How are mass and weight different?
- How does gravity affect acceleration?
1. Speed and Velocity: Concepts and Formulas
Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.
2. What is Acceleration? - Definition and Formula
This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.
3. Implications of Mechanics on Objects
Forces act on objects causing them to move. Mechanics is the field of science designated to the study of moving objects. This lesson describes how forces act on objects resulting in motion. Examples are used to describe how forces interact resulting in both simple and complex movement.
4. Newton's First Law of Motion: Examples of the Effect of Force on Motion
This lesson describes Newton's first law of motion, also known as the law of inertia. The interaction between force and motion is explained. Several examples are used to discuss the implications of this law on earth and in space.
5. Newton's Second Law of Motion: The Relationship Between Force and Acceleration
This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.
6. Newton's Third Law of Motion: Examples of the Relationship Between Two Forces
This lesson describes Newton's third law of motion. Examples are provided to illustrate how interacting objects experience forces. The lesson explains how objects accelerate as a result of force. Applications of Newton's third law are illustrated in nature, machines, and space.
7. Newton's Laws and Weight, Mass & Gravity
Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.
8. Albert Einstein & Time Travel Theory
This lesson is on Albert Einstein and how his work applies to time travel theory. We'll investigate Einstein's theories of relativity, examples of distortion of time on Earth and in deep space, and the prospect of time travel for humans.
9. Wheel & Axle: Definition, Facts & Examples
What is a wheel and axle and why is it effective? This lesson helps answer these questions while also providing several examples of common items using the wheel and axle design.
10. Catapult Physics: Principles & Equations
In this lesson, you'll learn how to apply motion equations and design a catapult. By the end of the project, you'll understand how to apply projectile motion equations to determine the maximum range for a catapult.
